    摘要: A high density magnetic bubble memory device comprises first magnetic bubble propagation tracks formed through ion implantation and second magnetic bubble propagation tracks formed of a soft magnetic material. Regions exclusive of those destined for realization of the second magnetic bubble propagation tracks are deeply ion-implanted. Gaps between the adjacent soft magnetic material films are also deeply ion-implanted. The second magnetic bubble propagation tracks may be shallowly ion-implanted or not implanted with ions.

    摘要: A magnetic bubble device has minor loops formed through ion implantation and used for storing information. As the density becomes higher, inside turn corner portions are formed on the minor loops. Dummy patterns having circular, triangular or other shapes are disposed in the vicinity of the corner portion. It is desirable that the minimum distance X between the dummy pattern and the propagation track satisfy the relation of 1.5 D.ltoreq.X.ltoreq.3.5 D, where D represents the diameter of a bubble.
